Method Fifty-five SHR rats with hyperactivity of liver fire were divided into model group Sancao Jiangya decoction SCD group Sini San decoction SND group and nifedipine group according to Latin square method Wistar-Kyoto WKY rats as control group. The macro characterization behavioral indexes and the systolic blood pressure SBP were collected. Enzyme-linked immunosorbent assay ELISA was used to detect the serum concentration of 5-hydroxytryptamine 5-HT angiotensin Ⅱ ANG Ⅱ norepinephrine NE after the rats were administrated for 4 and 6 weeks. Result Compared with control group the SBP and irritable degree increased revolving tolerance time decreased and serum 5-HT ANGⅡ NE level was higher in model group. Compared with model the SBP in SCD group and nifedipine group reduced after treated for 4 6 weeks weeks of age the SBP in SND group was stable and increased in the 16 weeks and then decreased. The symptoms of liver fire hyperactivity improved and it was not obvious in SND group and serum 5-HT ANG Ⅱ NE level was lower in SCD group compared with model group. Conclusion Fourteen-eighteen weeks is the stable time window of hyperactivity of liver fire. SHR 5-HT ANGⅡ NE may be used as the objective index of hypertension of hyperactivity of liver fire syndrome CB JYBZZ-XS-026 Tel xuexiaoxing2012@ 126. com * Tel wangwei@ bucm. edu. cn 97
